Aura Creations brings a variety of Solar Radiometers from G W Schleidt.
The Solar Radiometer was invented in 1873 by Sir William Crookes.
HOW DOES IT WORK?:
The solar radiometer consists of a glass bulb with a partial vacuum. Inside are four vanes which are mounted on a spindle. The vanes rotate when exposed to a warm light. More intense light increases the rotations....as many as 2000 per minute.
Each Solar Radiometer is bubble wrapped in a white gift box making it a unique Fathers Day, Office or Corporate Gift as well as a functional Home Decor Accent.
NOTE: Due to handmade nature, sizes (+- 1/4")and colors may vary.
Minor flaking from the vanes can be expected but does not affect the funtionality.
